Definitions
- the invention relates to increasing surface tension.
- Hot melt adhesive compositions are used in a variety of applications and on a variety of substrates including nonwoven webs, including tissue.
- Nonwoven webs are used commercially in a variety of applications including insulation, packaging, household wipes, surgical drapes, medical dressings, and disposable articles, e.g., diapers, adult incontinent products and sanitary napkins.
- hot melt adhesives When hot melt adhesives are applied to nonwoven webs it is desirable that the adhesive possess good flexibility (i.e., hand) and be free from bleed through. When used in applications such as disposable diapers, sanitary napkins and bed pad constructions, it is also desirable for the hot melt adhesive to be capable of transmitting liquid or moisture from the nonwoven fibers into the superabsorbent or fluff core substrates that are common in such applications. This property is known as wicking and is used to draw moisture away from the body and into the adsorbent core as quickly as possible after the nonwoven is wetted. Some hot melt adhesives are hydrophobic and repel moisture, rather than drawing moisture through the adhesive layer.
- EP 0 422 108B1 discloses disposable articles that include components joined by an adhesive composition.
- the adhesive composition can be sprayed-on a substrate.
- the adhesive composition includes a thermoplastic block copolymer, a tackifying resin and a plasticizer.
- WO 93/11187 discloses elastomeric pressure sensitive adhesive compositions used in label and tape manufacturing that exhibit cuttability and convertability.
- the pressure sensitive adhesive composition is rubber- or elastomer-based and includes surfactants containing polyethylene-oxide and polypropylene oxide blocks.
- EP 800 833 discloses disposable articles that include a hot melt adhesive composition that includes an olefin containing polymer, tackifying resin and from 1 to 25% surfactant.
- EP 800 833 asserts that the surfactant causes the adhesive composition to exhibit a contact angle of 90° or less and a reduction in surface tension of less than or equal to about 35-40 dynes/cm.
- the invention features an article comprising a nonwoven substrate and an adhesive composition that includes: a) a block copolymer comprising monomers selected from the group consisting of styrene isoprene, butadiene, and combinations thereof, b) from about 0.5% to about 10% by weight surfactant, and a tackifying agent.
- the adhesive composition has a surface tension of at least about 34 dynes/cm.
- the block copolymer is styrene-isoprene-styrene.
- the surfactant is nonionic. In some embodiments, the surfactant is selected from the group consisting of fatty acid esters.
- the surfactant can be glycerol monostearate.
- the composition includes from about 10% by weight to about 80% by weight of the polymer, from about 0.5% by weight to about 10% by weight of the surfactant, and from about 20% by weight to about 50% by weight of the tackifying agent.
- the composition further includes a plasticizer.
- the plasticizer includes a crystallizing plasticizer.
- the invention features an article that includes adhesive fibers that include an above-described adhesive composition.
- the adhesive composition provides a durable bond to a nonwoven article, including tissue articles, and exhibits flexibility, non-staining, and a viscosity sufficient to enable mass production.
- the adhesive also possesses exceptional thermal stability relative to moisture sensitive hot melt adhesive compositions.
- the hydrophilic nature of the adhesive composition facilitates transmission of fluids throughout nonwoven and porous articles that include the adhesive composition.
- the hot melt adhesive composition exhibits a surface tension of at least about 34 dynes/cm, more preferably at least about 40 dynes/cm, most preferably at least about 44 dynes/cm.
- the adhesive composition when present on substrate or incorporated in a substrate, provides an increase in the surface tension of the substrate such that the substrate can be more easily wet by a fluid, e.g., water, body fluid (e.g., blood, urine, and combinations thereof) and combinations thereof (i.e., the adhesive improves the wettability of the substrate).
- the adhesive composition includes a polymer and a surfactant.
- the polymer of the composition is block copolymer.
- block copolymers are useful in the hot melt adhesive of the present invention including A-B-A triblock polymers, A-B diblock structures, star block copolymers, (A-B) n radial block copolymer, comb polymers, as well as branched and grafted versions of such, wherein the A endblock is a non-elastomeric polymer block, typically comprising polystyrene and/or vinyl, and the B block is an unsaturated conjugated diene or hydrogenated version thereof.
- the B block is typically isoprene, butadiene, and mixtures thereof.
- block copolymers range in A block (styrene or vinyl) content from 0, as in the case of multi-arm (EP)n 8 100% diblock polymers to about 50 wt-%.
- the non-elastomeric A block concentration ranges from about 10 wt-% to about 45 wt-% with respect to the weight of the block copolymer.
- Block copolymers also range in diblock contents from 0, wherein the block copolymer is 100% coupled, to 100% diblock, as previously mentioned.
- the molecular weight of block copolymer is related to the solution viscosity at 77°F (25°C) of a given weight of polymer in toluene.
- the amount of block copolymer employed for determining the solution viscosity depends on the molecular weight. For relatively high molecular weight block copolymers, the solution viscosity is typically expressed as a function of a 10 wt-% block copolymer solution, whereas for more conventional and lower molecular weight block copolymers, a 25 wt-% block copolymer solution is employed.

- the increase in surface tension of the adhesive composition is preferably balanced with the surface tension of the substrate to be bonded. It may be advantageous to raise the surface tension of the substrate being bonded, particularly in the case of polyethylene films via film treatment, in order to simultaneously maximize the wettability of the hot melt adhesive composition and the bond performance.
- Test procedures used in the examples include the following.
- the peel adhesion failure temperature (PAFT) and shear adhesion failure temperature (SAFT) are determined as follows.
- An adhesive composition is coated onto Kraft paper by hand using glass rods or shims.
- the resultant coating is a 1 inch (2.5 cm) wide band that is about 8-10 mils or 0.008 to 0.010 inches 0.2 to 0.25 mm thick.
- the sample is then conditioned at room temperature for at least 16 hours.
- the samples are then placed in a programmed oven (Thermatron OV-6) and a 100 gram weight is clamped to a sample in the peel mode to test the PAFT and a 500 gram weight is clamped to a sample in the shear mode to test SAFT.
- the oven temperature is then increased from 25°C to 175°C at a rate of 25°C/hour.
- the sample is determined to have failed and the oven automatically records the temperature at which the sample fails.
- the reported result is the average failure temperature of from four to five samples.
- Melt viscosity is determined in accordance with the following procedure using a Brookfield Laboratories DVII+ Viscometer in disposable aluminum sample chambers.
- the spindle used is a SC-31 hot-melt spindle, suitable for measuring viscosity in the range of from 10 to 100,000 centipoise.
- a cutting blade is employed to cut samples into pieces small enough to fit into the 1 inch (2.5 cm) wide and 5 inches (13 cm) long sample chamber. The sample is placed in the chamber, which is in turn inserted into a Brookfield Thermosel and locked into place with bent needle-nose pliers.
- the sample chamber has a notch on the bottom that fits the bottom of the Brookfield Thermosel to ensure that the chamber is not allowed to turn when the spindle is inserted and spinning.
- the sample is heated to 350°F (177°C), with additional sample being added until the melted sample is about 1 inch (2.5 cm) below the top of the sample chamber.
- the viscometer apparatus is lowered and the spindle submerged into the sample chamber.
- Surface tension of a film of adhesive is determined using a set of dyne level marking pens, e.g., Accu Dyne TestTM (Diversified Enterprises). Each pen corresponds to a certain surface tension dyne level.
- the adhesive composition to be tested is drawn down into a film on a MYLAR film using a draw down square or Bird applicator.
- Various dyne levels are tested by drawing a line on the film and observing the behavior of the fluid dispensed from the pen.
- a dyne fluid beads up when the film has a lower surface tension that the fluid.
- the dyne fluid remains a film when the surface tension of the film is equal to or higher than the surface tension of the fluid.
- a result of "ok” indicates that the adhesive composition remained a film without beading up.
- a result of " ⁇ ” indicates that the adhesive composition beaded up.
- the contact angle is measured with the use of a goniometer, which has a microsyringe for dispensing accurate droplet sizes and a camera for photographing the angle of the liquid drop as it meets the surface of a film.
- the contact angle is measured as the angle between the film and the tangent of the liquid drop (i.e., at the interface between the fluid and the film) using analytical fluids such as Diiodomethane and water. The lower the angle, the more effective the coating is in transmitting (i.e., wicking) the liquid through the discontinuous adhesive layer.
